Costeño Beach Surf Forecast and Surf Report

Alright, grab your board and listen up. It’s Rusty here, and I’ve been staring at the charts for our stretch of coast, and honestly, it’s a bit of a mixed bag for the next couple of weeks. We’re not looking at any kind of epic swell event, but there are a few windows where it’ll be worth getting wet.

The first few days are pretty average. Monday the 17th and Tuesday the 18th are looking small and a bit messy, with light cross-onshore breezes. The energy is weak, with the combined swell energy around 706 on Monday morning but it dips quickly. We’ve got surf in the 4ft to 6ft range, but it’s not particularly clean. The water temp is 82°, which is pretty much spot on for this time of year, nothing weird going on there.

We’ve got a little window mid-week, on Wednesday the 19th, where it goes glassy. The wind drops right out, and we see those clean conditions with the swell around 4ft to 4ft from the NE. It’s small, but if you’re keen for a grovel on a longboard, that’s your best bet in the near term. That glassy water is a massive plus.

Then we hit a run of days from Thursday the 20th through to Saturday the 23rd where the swell picks up a touch, getting into the 4ft to 6ft range. The energy also builds, getting to a moderate level, with values like 481 on Saturday morning. But the wind is the issue. We’ve got onshore and cross-onshore winds, mostly light, but enough to put a bit of texture on the surface. There’s also the chance of thunderstorms in the afternoons, which can mess things up. It’s rideable, but you’ll be working for the clean ones.

Sunday the 23rd and Monday the 24th stay in that same pattern, with moderate energy and light cross-onshore winds. The swell holds around 6ft to 6ft. It’s nothing special, but there are waves.

Now, here’s the part that gets a bit grim. From Tuesday the 25th, the wave energy really starts to drop off. We see the swell drop back down to 4ft and the energy numbers fall into the low 100s. It’s just not doing much. This poor stretch looks like it’s going to last for a good five or six days. The conditions are poor, and there’s not a lot of power behind anything.

The one bright spot in the long range is Thursday the 27th. In the afternoon, the wind swings around and goes glassy again. We’ve got a 5ft NE swell with a period of 8 seconds, and the energy is around 358. That’s a moderate amount of energy. The comment says to expect good surf conditions, and with that offshore/glassy wind, it could finally be the cleanest waves we see in the whole period. It’s a long way out, so don’t book the time off work just yet, but it’s the most promising sign on the board.

After that, it’s back to the small, weak stuff. The energy drops right off into the low 100s and then below 100 by the end of the month and into September. The swell gets down to under 3ft, and it’s just going to be flat and dribbly. That last week is a write-off unless you want to practice your paddling.

So, for the best of what’s on offer, keep your eyes on that glassy Thursday morning the 19th for a small, clean session, and then look ahead to that Thursday afternoon the 27th, which has the best combo of size and clean conditions. That’s the standout. For everything else, it’s a bit of a grind. This isn't the time for beginners to be out chasing size; stick to the smaller, cleaner days. If the wind is up and the surf is messy, it might be more fun to get the kite out.

Rusty.
